Abstract
The present disclosure is directed toward systems and methods for generating a composite radiographic image that corrects effects of parallax distortion. A sequence of radiographic images—including a series of discrete exposures or image frames from a fluoroscopic procedure—may be acquired using a C-arm apparatus. An exemplary method may include receiving a plurality of radiographic image frames pertaining to a patient, identifying a region of interest on the image frames, cropping the region of interest from a plurality of image frames, selecting a plurality of sequential portions of cropped image frames, and stitching together the selected portions to form a composite image that corrects effects of parallax distortion.
